三相电压型PWM整流器定频虚拟磁链直接功率控制
Fixed Frequency VF-DPC of Three-phase Voltage-type PWM Rectifier
摘要
Abstract
To achieve stable and reliable control of PWM rectifier system, this text introduces a new kind of virtual flux direct power control based on traditional three-phase voltage direct power control. This control strategy replaces traditional switch table and Hysteresis comparison by introducing SVPWM modulation module, solving the problem of high and unfixed frequency in the traditional virtual flux direct power control, to reach the purpose of the fixed frequency. At the same time it can get voltage vector in any direction, with lower current distortion rate and the ability of anti-interference. The simulation results can prove the feasibility of the control strategy.关键词
